<p>A mixing block, for attachment to a combustion chamber in which a solid body or material is briefly subjected to high temperature and pressure by the detonation of an explosive gas mixture, is composed of three block-like parts clamped together by screws. This enables the relatively long channels subject to explosion stresses to be constituted of lengthwise bores in the middle block connected by milled short cross-connections. The protective cutoff valve is an automobile type valve set in the upper block piece, which can also have an insert of temperature resistant material adjacent to the mixing chamber portion of the middle block. The ignition device is not shown in the drawing, but is usually provided in the mixing block structure. In the section of the mixing block illustrated in the drawing only one of the gas connections to the mixing chamber (19) is shown. However, similar gas connections and channels are provided for other components to be led to mixing chamber (19) for mixing therewithin; the single drawing section depicting how each of the separate gas connections and channels leading to chamber (19) would be constructed, but only showing one for simplification.</p> |
